Writer Chiina Mieville, author of fantasy title The City and the City, and Peter F Hamilton, author of the Void trilogy have been campaigning for some time to get DRM removed.

When it happens users will not be restricted to using only one firm's technology to read purchased titles.

If you buy a DRM-encoded book via Amazon, you can only read it on a Kindle but cannot transfer the title to a Sony Reader, Kobo eReader or use it with Apple's iBooks.

However, some publishers are not sure if they should kill off DRM as it would encourage piracy.

Neill Denny, editor-in-chief of the Bookseller magazine, said that some publishers think that DRM is an impediment, and has been cracked anyway so isn't necessary. But others say that it continues to restrict piracy.

The book sellers are also aware that they need to come up with better business models or they will end up like the movie and film industry.
